推荐答案

使用Tomcat 7，更轻松地完成更新战争的任务而又不减少Tomcat的工作量.有多种方法可以做到这一点.

With Tomcat 7, the task of updating wars without taking down the tomcat is easier. There are multiple ways to do this.

我建议您遵循以下任一方法:

I would suggest you to follow either one of the below:

1. 使用Tomcat管理器GUI
2. 通过Tomcat的Deploy任务使用基于ANT的部署.

在上述任何一种情况下，您都需要将您的war文件从adweb.war重命名为 adweb ##.war和context.xml(如果需要)，然后上传到远程/本地tomcat设置.

In any of these cases, you would need to rename your war file, from adweb.war to adweb##.war, and context.xml (if needed) and upload to a remote/local tomcat setup.

每次您需要升级战争时，在重命名战争文件时只需使用比上一个版本更高的版本号即可.

Everytime you need to upgrade your war, just use a higher version number than the previous one while renaming the war file.

请注意，在执行热部署时，上下文路径/adweb也应更新为/adweb ##.

Note that, the context path /adweb should also be updated as /adweb## while performing hot deployment.

一旦成功部署了新版本(在管理器用户界面中指示)，您就可以停止/取消部署以前的版本.否则，tomcat仍将使用最新版本，并且所有新请求都将重定向到新版本.

Once, the new version is successfully deployed (indicated in the manager UI), you can stop/undeploy the previous version. If not, the tomcat will still use the latest version and all the new requests will be redirected to the new version.
